To all whom it may concerted I Be it known that L'PAUL A. BA OEL, a citizen of the United States, a' rcsident of Nutley, county of Essex, and Stateof'New" Jersey, have invented a certain Double Mil-l tijet Condenser, ot which the following is a" specification, accompanied by drawing.

This invention relates to multi-jet con-' densers, but moreparticularlyto adoub le condenser of that type, comprising one'condenser wlthin another.

' One object of the inventlon'is to enablea multi-jet condenser to be serve'd by two 'wa j ter supply pumps, so that: at light loads, 'or" water; one-puin'p'j in winter time with cold can b shut down.

Another object of the invention, is to en able the water discharged from one set of nozzles to be re-circulated by a second pump and supplied to the other set of noz-' zles, which is advantageous for instancei'i' case water has to be pumped a long distan' so that a large supply is not availablek Further objects of the invention will hereinafter appear, and' theinvention is shown in one of its preferred forms in the accompanying drawing, which is a side elevation partly in longitudinal section of a condenser.

the counter weighted flap valv J.

In accordance with this invention, two concentric sets of nozzles K and L are arranged wlthin the upper section or inlet head A, of the condenser, and in addition to the outer diffuser tube D, there is an inner concentric diffuser tube 0 preferably discharging into a separate tank P. The outer and inner sets of nozzles K and L direct convergent streams of water into the outer and inner diffuser tubes D and O respectively. The tail pipe Q of the inner diffuser O is providedwith the flap valve R and the gate valve S, which latter valve is adapted to be operated by the hand wheel T.

The sets or rings of nozzles K and L are preferably carried by separate water heads U and V, so that the sets of nozzles may be served 'byjseparate water supplypu'mps'W" respectively."Steam entersat 'the steam inlet-Y and' thecond'ense'r"casing is preferably? provided with anysuitable form of vacu-um'b'reaker Z; w v

The water'supply pump- Wpu1'np's water I from the supply ina inct which main is also "connected to the'intake b of the" supply pump -X anda valve cispreferably inserted in the main a.-'-As shown in the drawings", the intake of the supply pump X' is GOnnec'ted by the pipe d to the tank 1? and a valve 6 is'i nserted' in-this connection; The] pump "-;W- is connected by the "pipe to the water head V of the inner ring'o'f nozzles L and a Y valve 9 is inserted insaid pipe."' The pump X is connectedfby the pipe h to the water head of the outer ring otno zzlesK and a valve *0 is inserted in said pipe: A dis- "charge connection 12 havingthe valve 9 is also-connected to the pipe'h.

, In the operation ofthe apparatus, let it be assumed that the valve o the water" main a isclosed, 'andth'at the", water is being supplied-by the-pum JV to the inner concentric rlng of nozzles L which discharge convergent streams of water to the throat of the inner difiuser tube 0. The jets of water may be surrounded by the combining tube 9" having the guide vanes s and in such case, the lower guide vanes 25 of the comb-ining tube, are provided with the apertures tank P and supplies it to the outer concentric ring of nozzles K which discharge convergent streams through the apertures u in the combining tube to the outer diifuser tube D which discharges into the tank F. The flap valve R. on the tail pipe Q of the inner difius'er will close when water is not being discharged. In winter with cold water, the pump W may be shut down and then by closing the valve 6 on the pipe at leading to the tank P, and opening the valve 0 in the main supply pipe a, the outer ring of nozzles K only will be served by the supply pump X.

In case, as stated, water has to be pumped a long distance and a large supply is not available, the water discharged from, the inner ring of nozzles L may be re-circulated by the second plimp X which then takes its water from the discharge well P, as described and delivers it to the outer ring of nozzles K which discharge to a separate nozzles L, 6500 pounds oi s tank or We'll F and thence to Waste, through the over-flow pipe. I

As an example, let it be assumed that a given condenser whens'upplied'with 3,300 gallons at 7 O deg rees" temperature" will carry a load of 23,600 pounds of steam at 28 inches vacuum. Half of this water,"or'l6'50'" gallons in the inner ring, of the nozzles-L carry half the load, or 11,800 pounds or" mtheat ee-the water from =70 degreesto. 8 egrees 1 If, th h s is t.' de ee empe ate n her p p X t reus me wi l be c m 5 51 @1128,- nc es,ve uygnshea ingfthe ere: o 91%, de re t mpe tu e, Th tar; tal loadpthat would ,beca'r ed th 0on den e @Iier iqir 0 mm stea or f water-1 consumption of 1650 gal- Ions c rculated twice.
